Family Secrets by Judith Henry Wall

This is another book that won't make you any smarter - but it was enjoyable all the same. There are three sisters (who don't always get along), a mysterious letter found in a family Bible after their father's death (seems their paternal grandmother didn't die in childbirth!) and a mother who loves these three but needs to get on with her life (she moves to southern France). The sisters plan a trip to Montana to solve the mystery of granny. Along the way we find out more about their lives and problems. There were a few unexpected twists along the way - but not many.
